To aZZ whom it may concern.-

Be it known that 1, WILLIAM J. S'rINsoN, a citizen of the United States, and a resident of the city of London, in the county of Middlesex, in the Province of Ontario, Canada, have invented a 'certain new and useful Gas-Machine, of which the following is a specification.

This invention relates to a machine for generating acetylene gas; and it consists of the improved construction and novel combination of parts, as will be hereinafter first fully set forth and described and then pointed out in the claims.

Reference being bad to the accompanying drawings, Figure 1 is a central longitudinal sectional view of a gas-machineembodying my invention. Fig. 2 is a detail plan view of the generator, showing a battery or series of carbid-cases and attachments. Fig. 3 is a detail plan view of the roller shown inFig.2. Fig. i is a detail central cross-sectional view of the carbid-case and also of the carbid-holder contained therein. In this view a cross-sectional view of a guide, as well as a portion of the guiding and conducting pipe, is shown. ig. 5 is a horizontal sectional view on the line a a of Fig. A. Fig. 6 is a perspective view of the carbid-holder.

In the accompanying drawings the numeral 1 designates the generator-tank, which is divided into two chambers 2 and 3 by the inclined partition 4:, and said chambers 2 and 3 are filled with water to the height indicated by the dotted lines 5 and 6, respectively; but the inclined partition or bottom 4 is watertight and prevents the water from one cham- 1 her passing into the other, and 2 is a valve or gate which permits the removal of ash or other residue from the chamber 2.

7 designates a U-shaped pipe having one end inside the compartment 3 and the other end terminating outside of the water-tank. This pipe is for the purpose of maintaining the water-level in the chamber 3.

8 designates a pipe extending from near the top of the chamber 2 into'the chamber 3, and said pipe 8 extends slightly below the waterlevel 6 in said chamber 3.

' 9 designates a carbid-case closed at the upper end and open at the lower end, and secured to two sides of which and extending in a curved shape or handle above is the pipe 10,

and 11 is an opening in the carbid case 9, which permits the gas to pass from the carbidcase 9 to the pipe 10, and when said carbidcase 9 is placed in proper position in the generator-tank l the pipe 8 telescopes the pipe 10 at one side of the carbid-cas'e, as shown in Fig. 1.

9 designates a carbid-holder open at both ends and provided with a central partition 9, on which the carbid is placed.

9 designates perforations formed in the upper portion of the sides of the carbid-holder, and 9 designates a catch supported in the carbid-case 9, the lower angular end 9 of which may be adjusted under said carbid-holder 9 to secure the latter in said carbid-case 9 when desired.

12 designates an inwardly-extending guiding-flange secured to the inside of the generator-tank 1, and 13 represents curved recesses formed in said flange 12, to which the pipe 10 on the adjacent side of. the carbid-case 9 is fitted and'with which it is adapted to engage. This pipe 10 on one side of the carbidcase, being fitted to and adapted to engage witli the recess 13 in the guiding-flange 12 and the pipe 8 telescoping with said pipe 10 at the opposite side of the carbid-case 9, holds the latter in line or in an upright position when it is automatically lowering itself in said generator-tank 1.

14 designates a shoulder formed integral with or securedto the pipe 10'. I.

15 designates a sliding bar provided with a flange 16 at one end and with lugs 17 on the other end, in which lugs 17 the antifrictionroller 18 is pivotally secured.

19 designates a plate secured to the top of the generator-tank 1, and 20 designates a holder through which the sliding bar 15extends, and said holder 20 holds said sliding bar 15 in place andinline with the shoulder 14 on the pipe-1O as said sliding bar is adjusted backand forth, and 15? designates antifriction-rollers mounted inthe holder 20 and adapted to engage with the opposite sides of the sliding bar 15.

21 designates a shaft provided with pins 22, which are arranged in a helical curve around said shaft, and 23 designates a ratchet-wheel rigidly secured to said shaft. 4

24 24 designate brackets secured to the generator-tank 1 or other suitable support, in which the shaft 21 'is supported and rotates perfectly free.

25 is a bracket secured to the gasometer 26, and 27 'is a ratchetbar pivotally secured to and suspended therefrom and adjusted to engage with the teeth of the ratchet-wheel 23.,

28 designates a water-tank filled with-water to theheight indicated by the dotted line 29, in which tank 28 the gasometer 26 is vertically movable.

30 3O designate stop-rods secured to the wa-" ter-tank 28, which arrest the movement of the gasometer in order to prevent the lower end of the latter from risingv out of the water in the water-tank 28.

31 designates a water-sealing chamber located below the Watertank 28 and provided with a lip 32 for refilling or for overflow.

33 designates a gas-inlet pipe opening into and extending from the chamber 3 of the generator-tank 1 to the gasometer 26.

34 designates a hood secured to the upper end of the gas-inlet pipe 33, the lower edge of which hood extends a short distance into the water in the tank 28, and said gas-inlet pipe 33 opens into said hood above the water in said tank 28, and 35 designates a branch of said gas-inlet pipe 33, which extends a short distance into the water in the water sealing chamber 31.

36 designates a tube in which the opening or openings 37 are formed, and said tube is rig- .idly secured to the top of the gasometer 26.

38 designates a service-pipe which opens into the tube 36 above the water in the watertank 28, and said service-pipe 38 extends to the burners and is provided with a branch 39,

which extends for a short distance into the water in the water-sealing chamber 31.

4O designates a tube rigidly secured to the gasometer 26, and 41 designates a safety-pipe rigidly secured to the bottom of the water-tank 28, which extends upward in or telescopes with said tube 40.

42 designates a secondary or supplemental safety pipe which extends from the watersealing chamber 31 to the outside of the buildmg.

43 designates apipe which connects said secondary safety-pipe 42 with the service-pipe 38, and said connecting-pipe is provided with a valve 44.

The operation is as follows: A case 9 of carbid having dropped into the chamber 2 of the generator-tank 1, it is completely submerged in water, and the water coming in contact with the carbid in said case 9 gas will be generated, which passes out of said case 9 through opening 11 and into and through pipes 10 8, and

from the latter it bubbles up through the water into the chamber 3, and said gas is then conducted by the gas-inlet pipe 33 to the hood 34, and from the latter it again bubbles up through the water into the gasometer 26, which causes the latter to rise. As the gas is consumed said gasometer 26, as well as the ratchet-bar 27, is lowered, and as said ratchet-bar 27 is lowered it engages with the ratchet-wheel 23 on the shaft 21 and rotates the latter, together with the pins 22, and as said shaft revolves one of said pins 22 engages with the shoulder 16 on the sliding bar 15 and adjusts the latter from in under the shoulder 14 on the pipe 10. The

succeeding carbid-case to which said pipe 10 is attached then drops into the chamber 2, where further gas is generated, which passes to and causes the gasometer 26 to rise, as before described,,and as the gas is consumed again the gasometer lowers, as well as the rachet-bar 27, which engages with and rotates the ratchet-whee-l'23 and shaft 21, as before described. This moves the next succeeding pin in contact with the next succeeding sliding bar 15 to disengage it from shoulder 14 on the next succeeding carbid-case, which drops into the water in the chamber 2, and this is repeated so long as any carbid-cases remain charged. The gas passes from the gasometer 26 through the service-pipe 38 to the burners.

The safety-pipes 41 and 42 permit the gas to escape to the outside of the building if more gas is generated than the gasometer will hold, or if the gasometer should not rise as the gas passes thereto in this case the gas would pass down through the branch pipes 35 and 39 and bubble up through the water and into the water-sealing chamber, from which it would escape through the secondary or supplemental safety-pipe 42. As a result a simple, strong, durable, safe, and economical machine for generating gas is provided.

Having thus described my invention, I claim 1. In amachine of the class described, a carbid-case closed at its upper end, open at its lower end, and in one side of which an opening is formed, a carbid-holder open at the upper end, in the side of which perforations are formed, which is provided with a partition on which the carbid is placed, and which is supported and locked in place in said carbid-case, in combination with a pipe which is secured to said carbid-case,-the opening in the side of the latter permitting the gas to pass from said case to said pipe, substantially as and for the purpose set forth.
